在 JSON 架构中引用本地相对文件？

json java jsonschema json-schema-validator
2022-09-03 13:21:59

我正在为REST Web服务构建一个JSON。但是，架构已增长到1300多行，我想将其拆分为多个文件。我正在使用json-schema-validator版本2.1.8针对JSON示例响应文件夹对我的架构进行单元测试。

我知道您在当前文件中定义了导入类型，例如，但是如果我想将的定义移动到另一个文件，例如，那么我该如何引用它？{ "$ref": "#/definitions/MyBool" }MyBoolCommon.schema.json

我试过了 ，但都不起作用。{ "$ref": "Common.schema.json/definitions/MyBoolean" }{ "$ref": "./Common.schema.json/defintion/MyBoolean" }{ "$ref": "file://./Common.schema.json/definitions/MyBoolean" }

关于“common-js utils中的JSON Schema验证是否支持引用？”的答案似乎应该有效，但我似乎无法获得正确的语法。

我正在加载架构：

JsonNode mySchema = JsonLoader.fromReader(   new InputStreamReader(  JsonSchemaTest.class.getResourceAsStream( "/json/schema/MySchema.schema.json" )  )   );

然后用以下命令验证它：

JsonSchemaFactory.byDefault().getValidator().validate(   schema,   new InputStreamReader(  getClass().getResourceAsStream( "/json/sample/MyJsonSample.json" )  )   ).isSuccess();

FWIW看起来像这样：MyBool

"MyBool": {
    "type": "object",
    "properties": {
        "value" :{
            "type": "string",
            "enum": [ "true", "false", "file not found" ]
        }
    },
    "required": ["value"],
    "additionalProperties": false
}

当我不尝试提取时，架构会正确验证我的所有JSON示例。MyBool

我收到的异常是：

    level: "fatal"
    uri: "file:/Common.schema.json/definitions/MyBool#"

答案 1

您需要的是能够使用绝对URI引用文件。

假设您使用的是稳定版本（即2.0.2），请使用此方法加载架构。

给定文件所在的位置，请使用：

final JsonSchema schema 
    = factory.getJsonSchema("resource:/json/schema/MySchema.schema.json");

这意味着此架构中的URI解析将相对于此（加载）URI进行;所以，参考你的，你会做的：MyBoolean.json

{
    "$ref": "MyBoolean.json#/pointer/into/file"
}

例如，如果它位于，那么您将编写：/json/schema/subschemas

{
    "$ref": "subschemas/MyBoolean.json#/pointer/into/file"
}

父母也工作等。

请注意，如自述文件所述，2.1.x 是一个开发版本！我目前正在重新设计 API...


答案 2

以下解决方案对我有用。路径是相对于我运行mvn目标的位置而言的。

"items": {
                "type": "object",
                "$ref": "file:src/xyz/abc/lmn/DeviceRecord.json"
         }

以下是您执行 maven 目标的路径。file:
